Which is the correct algebraic expression after combining like terms? 6+8x-7-x

a 7x-1

b 7x+13

c 9x-1

d 9x+13

7x - 1 is correct after combining like terms

Step-by-step explanation:

6+8x-7-x

To simplify algebraic expression we combine like terms

In the given expression

-x or - 1x are same

8x and - 1x are like terms

6 and - 7 are also like terms

8x-1x = 7x

6 - 7 = - 1

So 7x - 1 is correct after combining like terms
